SAW-SET.

Specification of Letters Patent. Patented Feb. 16, 1915.

Application filed November 3, 1913. Serial No. 799,048.

. is simple in construction and which may be adjusted for use upon allkinds and sizes of saws and to set the teeth at any desired angle.

A further object of my invention is to construct the saw set in a numberof separable parts in order that it may be readily taken apart andpacked in small space for shipment or storage and also in order that ifany part should become broken it may be replaced at small cost andthereby avoid the necessity of obtaining an entire new tool.

With these and other objects in view, my invention will be more fullydescribed, illustrated in the accompanying drawing, and thenspecifically pointed out in the claims which are attached to and form apart of this application.

In the drawing: Figure 1 is a top plan view of my improved saw set,showing the manner of employing the same; Fig. 2 is an end view of thesaw set; Fig. 3 is a detail sectional view on the line 3-3 of Fig. 2;Fig. 4L is a perspective view of the saw tooth engaging jaws removedfrom the body of the saw set.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawing by the samereference characters.

The preferred embodiment of my saw set, as illustrated in the drawing,includes a body portion 10 in the form of a sleeve, the opening 11 ofwhich is preferably rectangular. This sleeve is provided at either sidewith bosses 12 providing sockets 13' to receive the reduced terminals 14of handles 15.

A U-shaped member, indicated as a whole by the numeral 16, has a bightportion 17 which is rectangular in cross section to fit snugly in thebore 11 of the sleeve 10, any possibility of movement in this bightportion thrdugh the sleeve being prevented by the laterally directedshoulders 18. The mem ber 16 is secured in place by a winged bolt 19which is threaded through a tapped bore formed in the sleeve 10 and intothe bight portion 17 of the member 16. The side portions 20 and 21 ofthe member 16 form gage jaws for regulating the set of the saw, as willbe later explained. These jaws immediately beyond the sleeve 10 convergeI slightly toward ea-oh other after which they are offset away-from eachother to extend in parallel spaced relation at their free ends, asclearly shown in Figs. 1 and 2.

A pair of pivotally connected co-acting saw tooth engaging aws aremounted in the bight portion of the member 16. These jaws 22 and 23 arepivotally connected by a pin 24: which extends through an offset,circular car 25 formed upon one end of the jaw 22 and which seatsbetween similarly formed spaced ears 26 of the jaw 23. These toothengaging jaws are so proportioned as to fit closely in the bight portionof the member 16 with the outer faces of their free ends bearing againstthe converging faces of the jaws 20 and 21 when in fully extendedposition. The opposed inner faces of the aws 22 and 23 are provided withsockets 27 to receive the ends of a helical spring 28 which tends, atall times, to maintain the jaws in separated position.

l/Vinged adjusting screws 29 are threaded through tapped bores formed inthe jaws 20 and 21 and the inner ends of these screws, which arepreferably somewhat rounded, engage in sockets 30 formed in the outerfaces of the jaws 22 and 23. It will therefore be seen that by propermanipulation of the adjusting screws 29, the said saw tooth engagingjaws may be moved toward or away from each other to adjust them forengagement with saws of varying thicknesses. The free end portions orparallel portions of the jaws 20 and 21 are provided with a series oftapped bores to receive gage screws 31. Each bore of the jaw 20 is inalinement with a corresponding bore formed in the jaw 21 and theadjusting screws 31 are al-o ways positioned in a pair of alined bores,as clearly shown in the drawing.

The manner of employing the above saw set is clearly illustrated in Fig.1 in which I show a conventional form of saw blade 32 having teeth 33.But slight description of this operation is therefore necessary. The sawblade is clamped in a vise or other suitable supportwith its teethdirected upwardly, as shown, the adjusting screws 29 turned to adjustthe saw tooth engaging jaws 22 and 28 toward or away from each otheras'may be necessary to cause them to closely en'- gage against oppositesides of the teeth and the gage screws -31 passed through the properbores of the gage jaws 20 and 21 and threaded toward or away from eachother to bring them into proper adjustment. When the parts are properlyadjusted in this manner, the'saw'teeth engaging jaws "are brought intoengagement with one of the saw teeth and the saw set rocked tothe rightuntil the right hand gage screw engages against the blade of the saw.The set isfixed upon the next tooth and rocked "toward theleftuntilstopped by the left hand gage screw. These gage screws are ofcourse setin such a-manner thatthe teeth bent .to

the right will be bent'to the same extent'as those bent to the left.

From the foregoing descriptiomit will be apparent that I have provided asaw set having a vast range of adjustment and one which may be readilytaken apart and packed in small space for shipment or storage.

' It will of course be understood that I do not wish to be limited tothe specific construction illustrated inthe drawing and described'in thespecification, as various minor changes in details of construction maybemade at any time without in the slightest 2.

4. A saw set including a sleeve forming a bight portion of the sleevewith its arms extendingto-providegage jaws, swingingly connected sawtooth engaging jaws seated I in the bight portion of the U-shaped memberandextending between the gage jaws,

In testimony whereof I affix my signature in presence of two witnesses.
